自1985年保护区计划（CRP）首次建立以来，土地退休作为减少农业生产对环境破坏的政策工具越来越重要。该项目的目标已经从最初的减少土壤侵蚀发展到实现多重环境效益。1996年，建立了保护区加强计划（CREP），通过将符合条件的农田限制在一个狭窄的地理区域内，以更经济有效地针对高优先级、环境敏感的地区。对于Illinois CREP而言，该区域是伊利诺伊河流域的百年洪泛平原及其邻近土地。减少场地外沉积物减少以改善水质是伊利诺伊州CREP和CRP的重要目标。除了确定资格之外，公共机关在设计土地退休工具时必须解决的一个重要问题是选择退休土地的决定规则的选择。环境效益和生态效益
Land retirement as a policy instrument for reducing environmental damages from agricultural production has been growing in importance since 1985 when the Conservation Reserve Program (CRP) was first established. The goals of the program have evolved from an initial focus on reducing soil erosion to achieving multiple environmental benefits. In 1996, the Conservation Reserve Enhancement Program (CREP) was established to more cost-effectively target high-priority, environmentally sensitive areas by restricting eligible cropland to a narrowly defined geographic area. For Illinois CREP, this area is the 100year floodplain and adjacent land in the Illinois River Basin. Reducing off-site sediment abatement to improve water quality is an important goal for both Illinois CREP and CRP. In addition to defining eligibility, an important issue that public agencies must tackle in designing a land retirement instrument is the choice of a decision rule for selecting the land to be retired.
